Lovely leather wrist strap... I want one... I need one... I must have one... NOW!
Great shots with the f/1.8
It is certainly sharp at f/2.2 and f/4 .
At f/1.8 it seems a little bit soft on the shots you posted.
I only have the one lens right now and I am looking to add a faster prime so would value your input.
@wornish, here is a test shot and about a 100% crop from yesterday at 1.8,
A bunch from around Watkins Glen, Didn't have my ND filter with me for the last falls shot
